Answer:
(0.4, -57.9)
Step-by-step explanation:
y = 3x³ + 12x² - 10x - 56
dy/dx = 9x² + 24x - 10 = 0
x = [-24 +/- sqrt(24² - 4(9)(-10))]/(2×9)
x = -3.033006505, 0.3663398379
d²y/dx² = 18x + 24
For minima, d²y/dx² > 0 which is at x = 0.3663398379
y = 3(0.3663398379)³ + 12(0.3663398379)² - 10(0.3663398379) - 56
y = -57.90544608
Answer:
Step-by-step explanation:
its not right equation
because
5X - 10 ≠ 2X - 4
Answer:
C
Step-by-step explanation:
because if you input 18.25 into the equation and solve you get and non-whole number of 2.608.
It is impossible to have 2.608 toppings on your pizza, <u>it has to be a whole number.</u>
All the other answers had whole numbers besides C, therefore C is wrong.
Question 3) 5x-26=18x This is how the equation is written if you substitute numbers for words and x for unknown number. 18x-5x =13x divide everything by 13 to get x= -2
Question 4) 63-x=2x+3 add x to each side and subtract 3 from each side to get 60=3x divide by 3 to get x=20
Question 5) -30x= -27x-63 add -27x to each side to get -3x= -63. Divide everything by -3 to get x=21
Question 6) 12x-18= 18+13x subtract 12x from both sides to get -18=18+x subtract 18 from both sides to get x=-36
Hope this helps!
The formula for displacement is:
<span>d=1/2(v0+v)t
If we multiply by 2/t we will have
2*d/t = v0+v
In order to find v0 we subtract </span><span>v (the final velocity)
2*d/t - v = v0
The final result is that: v0 = </span>2*d/t - v
